Title: Stepping motor
Inventor: MOCHIDA TAKASHI
IPC: H02K37/14
Filed: 1992-04-30
Abstract: PURPOSE:To get a stepping motor which can reduce detent torque without lowering holding torque by forming a chamfered section at the bend between a stator core and a magnetic pole tooth, and enlarging the distance from a rotor magnet to the magnetic pole tooth. CONSTITUTION:Chamfered sections COR2 are made at the bends of magnetic pole teeth 5AT and 5BT and 9AT and 9BT being bent at nearly right angles from the stator cores 5A and 5B and 9A and 9B, and the shapes of the chamfering are ones of the so-called C chamfering which shaves off the outside of the bends into the shapes of planes. It gets in the condition that the junction between the stator cores 5B and 9A is further separated from a rotor magnet 16 by the respective chamfered sections COR2. As a result, the magnetic flux from the rotor magnet 16 becomes hard to converge at the junction, which can reduce such detent torque as to prevent the motion of the rotor magnet 16.

Abstract: PURPOSE:To increase the number of handsets, to multiplex plural channels and to execute a communication by executing the communication to other station in the form of a digital signal through an optical transmission path. CONSTITUTION:The communication between the respective stations 1-3 is executed in the form of the digital signal through the optical transmission paths OC1, OC2, OC11, OC12. The communication executed by making a terminal station the starting point of a transmission is transmitted sequentially from a relay station 2 to a return station and transmission signals from the respective stations are overlapped. At this time, a signal from the station belonging to the same channel is applied added the same channel to discriminate from other channel. The contents of the communication on which the signals of all the stations are returned in the return station 3 and retransmitted from the relay station 2 and the terminal station 1. The respective stations take out only the signal of the channel to which the next station belongs of the returned signals and output from the receiver of the handset as a sound. Thereby, a simultaneous speech between the stations belonging to the same channel can be attained to increase the number of the connected handsets.

Abstract: PURPOSE:To prevent the mixing of a solution used for forming a first layer into a second layer thin-layer solution by carrying away a residual solution in a pre-process on a semiconductor wafer by a solution having the same composition as a subsequently contacted thin-layer solution. CONSTITUTION:A semiconductor-wafer carrier plate 20 is moved, and stopped at a position where a semiconductor wafer 9 is brought completely into contact with a thin-layer reaction solution chamber 60a, the semiconductor wafer 9 is shifted, and the semiconductor wafer 9 is covered with a thin-layer reaction solution at that time and the temperature of the wafer 9 is lowered only by 0.3 deg.C. The semiconductor-wafer carrier plate 20 is transferred similarly, cooling a growth boat, and the semiconductor wafer 9 is passed under mutually adjacent empty bathroom 70a and mother liquor 10b. A residual mother liquor 10a on the semiconductor wafer 9, to which a liquid growth process is completed in the thin-layer reaction solution chamber 60a, is washed together with carry-away and outflow to the empty bathroom of the mother liquor 10b on the passage of the wafer 9. Accordingly, the solution on the surface of the semiconductor wafer 9 is replaced with a solution 60b having the same composition as the solution on the surface of the wafer before the solution on the surface of the wafer enters just under a thin-layer reaction solution chamber 60b, thus preventing the mixing of two solutions.

Title: Cell switch
Inventor: SUZUKI KOJI
IPC: H04L12/933
Filed: 1990-05-28
Abstract: PURPOSE:To eliminate the need for increasing a line speed of a switch section by devising the switch such that a common memory circuit stores an input cell and each write/read control circuit uses the cell so as to process a time slot. CONSTITUTION:A common memory circuit 30 stores an input cell to addresses sequentially. A write control circuit 40 discriminates whether or not an address is idle based on destination information of the stored cell and writes a cell on a time slot of an input time division bus 71 sequentially to the common memory circuit 30. A read control circuit 50 reads a cell corresponding to a slot of an output time division bus sequentially form a relevant address based on destination information of the stored cell and gives the cell to the time slot to make the relevant address idle. Thus, it is not required to increase the line speed of the switch section and to facilitate multiple address communication. When lots of multiple address lines are accommodated, the effect of this system is especially improved.
